Track accessory heating powder sherardizing production line

Abstract

The invention relates to the field of railway track accessory machining, in particular to a track accessory heating powder sherardizing production line. The production line comprises a sherardizing furnace, a feeding device, a discharging device and a closed layer treatment device, wherein the sherardizing furnace is of a symmetrical independent furnace body structure; the feeding device is arranged at an end part of the sherardizing furnace; the discharging device is arranged on one side of the feeding device in parallel; the closed layer treatment device is arranged at a discharging tail endof the discharging device; the sherardizing production line is provided with matched feeding and discharging facilities, the sherardizing furnace adopts a double-furnace-chamber design of a symmetrical structure, the furnace body is good in sealing and heat insulation performance, and meanwhile, a bearing is cooled through water cooling; the closed layer treatment device can passivate and close the railway track accessories again after the product is subjected to a sherardizing treatment, the corrosion resistance and rust resistance of the railway track accessories can be further enhanced, meanwhile, the sherardizing production line is high in automation degree and small in personnel occupation, and the improvement of the overall benefits of enterprises can be promoted.

Description

technical field [0001] The invention relates to the field of railway track accessories processing, in particular to a track accessories heating powder galvanizing production line. Background technique [0002] Railway fittings are an integral part of the railway line, including track pressure plates, elastic strips and rail pressure devices. As an integral engineering structure, the track is laid on the roadbed and directly bears the huge pressure of the rolling stock and its load. Under the power of the train running, its various components must have sufficient strength and stability to ensure the safe, stable and uninterrupted operation of the train at the specified maximum speed. [0003] As we all know, the working environment of railway track accessories is complex and mostly quite harsh. Therefore, the stability and corrosion resistance of railway accessories are the key to the long-term normal operation of railways. Railway fittings are usually galvanized to improve ...

AI Technical Summary

Problems solved by technology

[0004] At present, the factory basically uses a single sherardizing furnace to complete the sherardizing treatment of railway track accessories. Most of the current sherardizing furnaces use a single furnace chamber structure with one-sided entry and exit. All the sherardizing furnaces are started, resulting in a great waste of energy; at the same time, the heat insulation effect of the existing zincizing furnace is poor, and there is no forced cooling facility. , which seriously affects the production efficiency of sherardizing, and the sealing of the furnace body is not good, the heat utilization rate of the furnace body is low, resulting in unnecessary waste of energy, and the existing zincizing furnace does not have supporting special feeding and discharging facilities. The efficiency is low, the operation is cumbersome, and multiple people are required to cooperate to realize the material in and out; at the same time, most of the current sherardizing production lines do not further process the railway fittings, which makes the corrosion resistance and rust resistance of the railway track fittings average. However, compared with the harsh working environment of railway track accessories, the current corrosion resistance and rust resistance are still unsatisfactory
